I have been riding and training normally with our lot of concern, he does kick himself and over reach so have him in splint boots and bell boots. I have worked mainly at a walk and trot but last night I tried to canter -in the arena he refused - put his head up and trotted very quickly. So I took him outside to a flat grassy area and was able to have him pick up the canter almost immediately. Here is the problem - he throws his right front leg out to the side in a slapping motion and wants to come to a stop after a few strides and then balks at moving forward at any gate. We did two short canters and then walked to cool off.
Is the cantering issue a side effect of the swollen pastern, a balance issue? I have checked and rechecked tack - not an issue and have not lunged at a canter.
